How does coal affect pollution?
Coal accounted for 39 percent of carbon dioxide emissions in 2004 (behind oil) but is expected to pass oil for the No. 1 spot in 2010, according to the EIA. Even if the United States were to replace every incandescent bulb in the country with compact fluorescents, the benefits would be eradicated by the carbon dioxide from two coal-fired plants over a year, said Ed Mazria, founder of Architecture 2030. The nonprofit encourages builders, suppliers, and architects to move toward making carbon neutral buildings by 2030.
